I received lots of good suggestions for v2 of the series, and the
patches needed a rebase. Thanks!

So far 33 of the 44 patches have a Reviewed-by. The patchwork link
above shows which patches have been reviewed.

For reference, here is the cover letter for v2 of the series:

Francisco Jerez (16):
  i965: Define symbolic constants for some useful L3 cache control
    registers.
  i965: Adjust gen check in can_do_pipelined_register_writes
  i965: Keep track of whether LRI is allowed in the context struct.
  i965: Define state flag to signal that the URB size has been altered.
  i965/gen8: Don't add workaround bits to PIPE_CONTROL stalls if DC
    flush is set.
  i965: Add slice count to the brw_device_info structure.
  i965: Import tables enumerating the set of validated L3
    configurations.
  i965: Implement programming of the L3 configuration.
  i965/hsw: Enable L3 atomics.
  i965: Define and use REG_MASK macro to make masked MMIO writes
    slightly more readable.
  i965: Implement selection of the closest L3 configuration based on a
    vector of weights.
  i965: Calculate appropriate L3 partition weights for the current
    pipeline state.
  i965: Implement L3 state atom.
  i965: Add debug flag to print out the new L3 state during transitions.
  i965: Work around L3 state leaks during context switches.
  i965: Hook up L3 partitioning state atom.
